The main objective of the proposed research is to develop a simulation method in which a physical scaled model of a high-rise**building will be tested in a wind tunnel testing facility. The flexibility and energy dissipation mechanism of the scaled model will be**represented as a computer model. The computer model and the physical model will interact with each other in real time through**sensors feedback and control of an electric actuator. The development of the simulation method is expected to greatly simplify**testing model preparation and calibration of model parameters such as stiffness and damping ratio, because these will be**modelled numerically. The research project is aimed at substantially reducing the testing cost (machine time and engineering time)**of the industry partner, which will allow further wind tunnel testing opportunities.

本研究的主要目的是开发一种模拟方法，在该方法中，将在风洞试验设备中对高层建筑的物理缩尺模型进行试验。比例模型的柔性和能量耗散机制将 ** 表示为计算机模型。计算机模型和物理模型将通过传感器反馈和电动执行器的控制在真实的时间内相互作用。模拟方法的发展有望大大简化试验模型的准备和模型参数（如刚度和阻尼比）的校准，因为这些参数将采用数值模拟。该研究项目旨在大幅降低行业合作伙伴的测试成本（机器时间和工程时间）**，这将为进一步的风洞测试提供机会。
